Sockets from 4GL ??
I need to create a socket connection, send and retrieve a message from a remote server. All our code is Informix 4gl ( Version 7.X ). I can call a C program using the RUN command, but I need to get the return message back into the 4gl code. Any ideas would be appreciated.

There are at least two different sets of C code that you might write. 1. C code which does the socket connection/communication from within the I4GL program - probably some interface functions using the same basic code as in the C program which you call. 2. General purpose I4GL-callable C code which runs another program, reads the output from that program and returns it in a form which I4GL can digest. Neither is particularly complex, though handling arbitrary quantities of output in 2 is painful. -- Jonathan Leffler (jleffler@informix.com, jleffler@earthlink.net) Guardian of DBD::Informix v0.60 -- see http://www.perl.com/CPAN #include <disclaimer.h>
